Massachusetts House of Representatives' 1st Essex district

Massachusetts House of Representatives' 1st Essex district in the United States is one of 160 legislative districts included in the lower house of the Massachusetts General Court. It covers part of Essex County. Republican James Kelcourse of Amesbury served the district from 2015-2022. Following Kelcourse's resignation in late-June 2022, the seat remained vacant until the election of Democrat Dawne Shand of Newburyport. Rep. Shand took office on January 4, 2023.

Following redistricting efforts in 2021, the 1st Essex shifted slightly west. The district now includes the towns of Merrimac and Salisbury; the city of Newburyport; and part of the city of Amesbury. Previously, the 1st Essex District included all of the city of Amesbury.
